LOOlVl-STOPPING AND AUTOMATIC BELT-SHIPPING DEVICE.

SPECIFICATION forming part of Letters Patent No. 688,254, dated December3, 1901.

Application filed July 2,1901. Serial No. 661824- (No model.)

To all whom it may concern:

Be it known that I, AUGUST LAUSTER, a citizen of the United States,residing at 118 River street, city of Paterson, in the county of Passaicand State of New Jersey, have invented certain new and usefulImprovements in LoomStopping and Automatic Belt-Shipping Devices, ofwhich the following is a specification, reference being had therein tothe accompanying drawings.

The object of my invention is to provide an adjustable loom-stopping andbelt-shipping device for looms, a device which may be applied to Germanor American looms, a device that will be simple, practicable, durable,and inexpensive, and that will be especially adapted for ribbon-looms ofany known description.

A further object is to produce an adjustable device for stopping loomsthat will render impact between the stopping device and the other partsof the loom practically noiseless, though forceful.

In a ribbon-loom where many shuttles are employed in carrying the weftthrough the difierent sets of warps when a break occurs while theshuttles are passing through the sheds the forward movement of thebatten causes considerable damage, and the principal object of myinvention is to produce a device which will stop the forward movement ofthe batten simultaneously with the breaking of any part of the loommechanism,which would result in the damage aforesaid, and to produce adevice so adjustable as to regulate the distance from the breast of theloom at which the batten may be stopped. In some instances it may bedesired to stop the batten at a point farther from the breast of theloom than might be required in other cases.

The invention consists in the novel construction, arrangement, andcombinations of parts hereinafter described, and set forth in theclaims.

In the drawings, Figure l is a side view of a loom, showing the bat-tenand breast-beam in section to illustrate the arrangement of my device.Fig. 2 is a top view of portion of a loom in running order, parts beingbroken away, and Fig. 3 is the same as Fig. 2, showing the position ofmy device when there has been a smash-up or breakdown and my deviceforcing the belt from the fast to the loose pulley of the loom. Fig. 4is a side view of a loom, part sectional, showingthe device forsimultaneously stopping the movement of the batten and shifting the beltand means for protecting the ribbon; and Fig. 5 is a plan View of aportion of a loom with my automatic means for simultaneously stoppingthe movement of the batten, shifting the belt, and protecting the ribbonapplied thereto.

In the drawings, A is the loom-frame; B, the batten; B, theshuttle-holder and shuttle; B the rack; B the lay-sword; B, theconnecting-rod between the batten and the crankshaft of the loom; O, thebreast-beam; D, the stopping-arm. D and D are the adjustable parts ofthe braces which connect the arm D and the rack 13*.

His the driving-shaft, having the pulley h. H is the loom-shaft, havingthe loose pulley h and a tight pulley 72, A driving-belt 72, passesaround the driving-pulley on the shaft H and around the tight pulley hon the loomshaft.

The brace D is secured to the rack. B by the screws 01. The braces D andD are provided with longitudinal slots and are secured together wheredesired by a screw d, which is part round and part square.

An adjustable stop-screw d is screwed into the arm D, and a stop-nut 61around the pin 61 is screwed up against the arm D On the end of thestop-screw d is secured a rubber head d.

A hole d in the arm D is provided with screw-threads, and there is aslot (1 in the braces D and D A bar E passes through an opening in thebreast-beam C and is provided on its outer and upper face with atransverse slot e To its inner end is secured an impact-receiving memberprovided with various offsets e,e,and e and with an opening 6, throughwhich the ribbon being woven is adapted to pass.

On nearly all ribbon-looms there is but a small space between theribbons being woven. The ribbons pass over rods or rollers, which areheld in brackets secured to the inner side of the breast O of the loomand downwardly between friction-rollers to the beam upon which they arewound. It is thus obvious that in that class of looms no stopping devicecould be operated by the action of the lay without striking the ribbonpassing downwardly over said roller andinside of the 100mbreast to thebeam upon which it was being wound. For instance, in Fig. 2 of thedrawin gs,if the ribbon were shown it would hide the central portion ofthe impact-receiving member, as it would pass firstover the rod orroller just described, which is located above said impact-receivingmember, before it would pass through the opening a in saidimpactrece'iving member, and then to the frictioni'ollers and to thebeam upon which it is wound. The ribbon is not shown in either Fig. 2 orFig. 3 in order that the impact giving and receiving member and theoperation thereof might be clearly shown. Neither is the rod or rollershown over-which the rib: hon passes prior to its downward passagethrough the opening 6 in the impact-receiving member.

It will be observed by reference to Fig. 1 that theimpact giving andreceiving members are considerably lower than the upper surface of theloom-breast O. The rod over which the ribbon passes is secured tobrackets practically in the line with the upper surface of the breast Oand a short distance from the inner face of the same, so that the ribbonpasses over said rod or roller and between it and the inner face of thebreast C, then downwardly and through the opening 6 in theimpact-receiving member, and so on to the beam which receives it.

A break or interference with the rack-operating mechanism is apt tooccur during any partof the traverse motion of the rack or during anyperiod in the motion of the shuttle.

If the break should occur while the shuttle is in the middle of thewarp-shed, it is obvious that the impact-giving member would strike theimpact-receiving member about in the center without injury to theribbon, and as all ribbons on that class of looms pass downwardly, asabove described, it would be impossible to have a loom-stopping deviceof this class that would be practicable unless it had means forprotecting the ribbons.

On the bar E between the impact-receiving member and the inside of thebreast-beam O is a spring 6 that tends to force the impactreceivingmember a short distance away from the breast-beam, as shown in Figs. 1and 2. The impactreceiving member is of such a length from extremity toextremity that if a break or disarrangement of therack-operatingmechanismshould occur at any time during the traversemovement of the rack or while the shuttle is passing through thewarp-shed thestopping-arm D, which is secured to the rack pass entirelyclear of said impact-receiv ing member on the inner end of the arm E.

A guide-plate e is secured to the breastbeam 0, and through an openingtherein the outer end of the bar E projects, as shown in the drawings.

A square sliding bar F is supported and adapted to be moved laterally inbearings f f, which are screwed into the outer-side of the breast-beamO. This lateral movement of the sliding bar F is caused by the tensionof the springf which surrounds said bar F betweenthe fixed collar] andone of the bearings f, as shown in Figs. 2 and 3.

On one end of the sliding bar F is formed a nosef, which is adapted topass down over the outer end of the bar E, as shown in Figs. 1 and 2,when the impact-receiving member of the bar E is pressed away from thebreastbeam O by the expansion-spring 6 When the stopper-arm D and itsru'bber headed screw strikes the impact-receiving member on the innerend of the bar E, the bar E is forced outwardly through the breastbeam,and the slot 6 coming opposite the nose f the nose f is released fromthe bar E, and the spring f forces the sliding bar F laterally, and theforked or crescent-shaped memberf on the end of the bar F by engaging apin 9 on the belt-shipping bar Gand the fork g thereon ships the belt77, from the fast pulley 71, on the loom-shaft H onto the loose pulley hthereon, thus stopping the loom.

It will be seen by reference to Figs. 4 and 5 that the ribbons beingwoven pass over rollers t', mounted in brackets I, which are secured tothe breast-beam O, and thence downwardly between tension-rollers u and nto take-up rollers u. To avoid the striking of any of these ribbons by astop device is one of the objects of my invention and is accomplished byhaving an impact-receiving member provided with means, such as theopening 6 for protecting said ribbon. Only the ribbon or ribbonswhichwould be so struck by theimpact-gi-ving member of astop device arepassed through or protected by the impactreceiving members, as shown inFigs. 5 and 6. The other ribbons would pass in the usual manner over therollers t' to the beam or take up roller 'Lt.

My invention both prevents the forward movement of the batten when abreak occurs and simultaneously shifts the belt from the fast to theloose pulley on the loom-shaft.
